XmeGetDirection(3X) UNIX System V XmeGetDirection(3X)
NAME
XmeGetDirection - A compound string parse procedure to
insert a direction component
SYNOPSIS
#include <Xm/XmP.h>
XmIncludeStatus XmeGetDirection(
XtPointer *textinout,
XtPointer textend,
XmTextType type,
XmStringTag tag,
XmParseMapping entry,
int patternlength,
XmString *strinclude,
XtPointer calldata);
VERSION
This page documents Motif 2.1.
DESCRIPTION
XmeGetDirection is a compound string parse procedure (a
function of type XmParseProc). It is suitable for use as an
XmNinvokeParseProc procedure in an XmParseMapping data type.
XmeGetDirection is triggered when the implicit direction of
the current character in text being parsed is different from
the direction of the previous character. The function
assumes that text_in_out points to the character whose
direction has changed. It creates a compound string with a
component of type XmSTRINGCOMPONENTDIRECTION that
specifies the direction of the character at the text_in_out
position. The argument text_in_out remains unchanged.
text_in_out
Specifies the text being parsed. The value is a
pointer to the first byte of a character whose
implicit direction is different from that of the
previous character. When the parse procedure
returns, this argument is not set to a value
different from the input value.
text_end Specifies a pointer to the end of the text_in_out
string. If text_end is NULL, the string is
scanned until a NULL character is found.
Otherwise, the string is scanned up to, but not
including, the character whose address is
text_end.
type Specifies the type of text and the tag type. For
locale text, type has a value of either
XmMULTIBYTETEXTor XmWIDECHARTEXT. For charset
text, type has a value of XmCHARSETTEXT.

tag Specifies the tag to be used in determining the
character direction.
entry Specifies the parse mapping that triggered the
call to the parse procedure.
pattern_length
Specifies the number of bytes in the input text
that constitute the matched pattern.
str_include
Specifies a pointer to a compound string. The
parse procedure creates a compound string to be
included in the compound string being constructed.
The parse procedure then returns the compound
string in this argument.
call_data Specifies data passed by the application to the
parsing routine.
RETURN
This function returns XmINSERT, indicating that the parsing
routine should concatenate the result to the compound string
being constructed and continue parsing.
